| Description | Some time ago Harrison wrote to Messrs Cassell about some colour printing work. Edwin Bale then advised Harrison to communicate with the Messrs and enquire about their three colour printing. The Society has a paper on colour vision illustrated by a number of colour spectra. The subjects are eight oil paintings with bright colours. If the Messrs thanks their process likely to be adaptable to the faithful reproduction of these, Harrison would be glad to hear from them, with particulars on the process. |
